lpplicatin led September 26, 1919'. Serial I0. 326,661.

To all lwllfofrtz't may concern:

Be it known that I, AncHIE L. HUremN- soN, a citizen of the UnitedStates, and a resident ofthe city and county of San Francisco, State ofCalifornia, have invented a .new and useful Improvement in Window-Frames, of which the following is a specification.

The object of my invention is to provide a window of the sliding sashtype, the frame of which window is pivoted wlthin the casing or frame ofthe window opening, so that when lthe window is to be cleaned, it may beswung into the room for giving convenient access to both sides of theglass.

And thel further object of my invention is to provide means, incombination with the type of window mentioned whereby the crevicesbetween the sash and the window-frame will be effectively closed, thatis rendered Weather tight.

I attain my object by the construction illustrated in the accompanyingdrawings in which Figure 1 is a perspective of a window casing or framehousing the window opening, and having pivoted therein, on a verticalaxls, centrally located, a swinging sash frame Erovided with the slidingsashes; parts being roken away to disclose structural features.

Fig. 2 is a plan section taken on the broken line 2 2 of Fig. l;

Fig. 3 is a section taken on the broken line 3--3 of Fig. l;

Fig. 4 is a detail ci a convenient type of means for pivoting the sashframe in the window frame;

Fig. 5 is a fragmental sectional detail on the broken line 5 5 of Fig.2;

Figs. 6 and 7 are details of construction of the Weather-strip elements.

Fig. 8 shows a fragmentary perspective view of the lower right handcorner ofmy window frame as shown in Fig. 1, and-illustrates theprovision of means connecting the overlapping weather stripseoperatively with each other, so that'they may be opened and closedtogether. i

a designates the window casing, or permanent frame housing the edges ofthe window opening; b, being the sill, and c, the lintel. This framewill be referred to as the window-frame to distinguish it from thesashframe al. The latter is pivoted in the window-frame by havingsecured to its u per and lower horizontalmembers, pivot p ates @,thepivots of which bear in socket-plates f, secured to the hntel c and sillb of the window-frame.

In the sash-frame slide the sashes g', h. The sash-frame may be made ofmetal as illustrated more clearly in Fig. 2; the stiles being formed asat i so as to provide vertical grooves for the sashes g, z, to slide in.The

stiles of the sash frame are made on the exterior with boxes j, or inother words with hollows' in which to vhang the weights c, connected bycords Z running over pulleys m l(see F ig. 5) with the upper and lowersashes, respectively; and balancing such sashes, as, usual, so they maybe readily moved.

On the exterior of the boxes j, may be r0- vided box-like slots oforholding weat erstrips p. These are adapted-to bear on the sides ofthe window-frame so as to keep out the weather, the surfacesof the sidesof the window-frame against which the weather-` strips p bear beingconcaved as shown at n, in Figs. 1 and 2, so as to provide a path forsaid weather-strips, and thus permitting and facilitating the rotationof the sash-frame in the window-frame.

In order to provide an effective closure of the crevices between'theadjacent members of the window-frame and the sash-frame position, thatis in registration with the former, the sides of the window-frame areprovided with vertical hinged weather-bars g and the lintel and sillthereof have horizontal hinged weather-bars r; and when the sash-frameis arranged in its normal position said weather-bars are so arranged asto bear against the sides and top and bottom of the sash-frame.

Weather-strip elements as g and r may be provided on both the insideand-outside of the window, since access to those on the outside is-readily obtainedthrough the window, by raising and lowering the sashes.

In order to assure eiiicient weather-tight construction, I prefer to cutaway the exterior members d Vof the sash-frame at. their top and bottomends as at s, so that the horizontal weather-bars 1' may be arranged in,and flush with, said cutaway ends, and the vertical weather-strip bars gmay then be folded over the horizontal weather-strip bars 7' and saidmembers d.

The hinges t may be of some convenient commercial spring-hinge typeadapted for holding the weather bars q against the sideS sist ofproviding the hinge-pin t of the weatherstrip element g with a segmentgear u meshing with a worm-screw c on Athe hinge-pin w of theweather-strip element fr.

I claim:

In a window, comprising a frame in the window opening, asash-framepivoted for rotation vin said window-frame, and upper andlower sashes slidable in the sash-frame, boxes on the exterior of the,sash-frame, means contained in said boxes by which the window sashesare suspended and balanced, weather-strip elements on the exterior ofsaid boxes, and auxiliary weather-strip elements carried by oneof saidframes and adjustable to cover the crevices between the adjacent membersof the window-frame and 'the sash-frame.

2. In a window, comprising a frame in the window opening, a sash-framepivoted for rotation in said window-frame, and upper and lower sashesslidable in the sash-frame, boxes on the exterior of the sash-frame,weights suspending and balancing the window sashes, the weights hangingin said boxes, weatherstrip elements on the exterior of said boxes, andauxiliary weather-strip elements carried by one of said frames andadjustable to cover the crevices between the adjacent members of thewindow frame and the sash-frame.

3. In a window, comprising a frame in the window opening a sash-framepivoted for rotation in said window frame, and upper and lower sashesslidable in the sash-frame, boxes on the exterior of the sash-frame,weights suspending and balancing .the win-` dow sashes, the weightshanging in said boxes, weather-strip elements on the exterior of saidboxes, weather-bars hinged to both sides and the top and bottom of thewindow-frame, and ada ted for being adjusted to overlap the yront facesof the lsides and the to and bottom of the4 sashframe, when the latteris in its normal position. l

4.
